Any ideas?????

Hi ladies! I just have a question. My hubby and I are TTC #1 going on 4-5 months now. I've started taking VitaFusion PreNatal gummies at least 1 month ago. But they don't have Iron. I have no OB/GYN yet but I'm just wondering if you ladies know if I can switch to different PreNatals without finishing these???? Thank you.
